Does the Caspian High Capacity frame use the standard 1911 grip panels, or is there a difference. If there is a difference, then what is the reason they won't fit.

I thought they were the same. But I know the Para Double Stack is very different and the grips are definitely different. But I don't think that the Caspain HC is a double. Just a lack of knowledge on my part and I can't seem to find the answer on the web.

I know a guy with one, he said everything about it is different than a regular single stack or hi cap frame, different mags, mag release, grip safety, grips, mainspring housing, his is 1st generation though, the newer ones may be different , probably best to call caspian
